I made up my mind and replaced the ESU sound decoder with Zimo plain DCC decoder in the GP15. One of each pair of Gensets became a dummy. That permits the combinations of Genset/Genset(D), GP15-1/Genset(D) and GP38-2/Genset(D). That is a nice collection of choices seen in the LA basin without speed matching problems and only one drive noise. Finally became a SW1500 a dummy too. I like the prototypical combination of GP15-1/SW1500(D).
